Compact 12G-SDI Fiber Converter with Loop-Out Tally RS485 Control

Overview

The LNK-M12G-1V1T1D is a miniature 12G-SDI fiber converter built for broadcast, live

production, and OB vans. Supporting 12G/6G/3G/HD/SD-SDI, it enables real-time 4K UHD video

with embedded 8-channel audio to be transmitted over fiber up to 20km or more. With Tally signal

and RS485 backward channel, it ensures smooth studio-to-camera communication. Its palm-sized

design, low power (2W), and hot-plug support make it an ideal solution where space and reliability

are critical.
